Track clipboard copies during your session. Search, re-copy, and organize snippets using the Clipboard API.
The tool automatically records everything you copy to your clipboard.
Scroll through your recent clipboard entries in reverse order.
Click on any previous clipboard item to copy it again.
Clipboard History Manager keeps a running list of the text you copy while you work with it, so you can search past snippets and re-copy them with one click. It records copies made inside the page and, when you allow it, reads the system clipboard through the Clipboard API, which requires HTTPS or localhost. The thing most people get wrong first: browsers provide no event when the system clipboard changes, so copies you make in other applications do not stream in live. They are captured only when the page reads the clipboard, and only after you approve the clipboard-read permission prompt.
A concrete input and expected output from the current implementation.
Input
Copy the text "Meeting at 3pm - Room 401" in any other application, then click anywhere on the tool's page so it reads the clipboard.
Expected output
The history gains one entry showing exactly "Meeting at 3pm - Room 401". Clicking that entry replaces the system clipboard with the identical string, ready to paste anywhere.
The tool stores the clipboard text it reads and replays that text verbatim on re-copy. It neither reformats nor truncates what it captured, so what you copy is what you get back.
Copies you make while the tool's page is focused fire the page's copy event, so the tool can record them immediately. Copies made in other applications sit on the system clipboard until the page calls navigator.clipboard.readText(), and that call triggers the browser's clipboard-read permission prompt. If you deny the prompt, the tool sees only in-page copies for the rest of the session.
Every stored snippet is plain text, and search filters that list by the text the entries contain. Re-copying calls navigator.clipboard.writeText() with the stored snippet, replacing whatever is on the system clipboard with that exact text. Writing requires a focused page in a secure context, but unlike reading it generally raises no permission prompt in mainstream browsers.
Only what the page reads at the moment it reads. Browsers do not notify pages when the system clipboard changes, so there is no live stream from other applications. Approve the clipboard-read prompt and bring the page to focus to trigger a read; text copied and then overwritten before that read is lost to the tool.
No. Reading and writing happen through the Clipboard API inside the page, and nothing is uploaded to a server. The tradeoff is that history is not persistent: the tool holds your snippets for the session, and closing the tab discards them.
